I ROTARY CH URN.

SPECIFICATION forming part of Letters Patent No. 699,101, dated April 29, 1902. Application led February 2, 1901. Serial No. 45,800. (No model.)

at Centralia, in the county of Marion l andl State of Illinois, have invented a new and useful Rotary Churn, of which the following' is a specification.

My invention relates to animprovement in a rotary churn; and the object of my invention is to provide a churn which will revolve about a shaft counterbalanced by adjustable weights on the other side of. the shaft, Whereby the weight of the churnand contents are equalized, and the power required to operate the shaft and churn is therebymaterially reduced. This same object may also-be accom-4 plished by adjusting a duplicatelchurngon the opposite side of the shaft with 'the contents counterbalancing instead'of the'adj ustable weights. I attain this object bythe mechanism in the accompanying drawings, illustrating the same, in Which- Figure l is an illustration of the entiremachine with the adjustable weights, and Fig. 2 is an illustration of the entire machine with the double churn instead of weightson'one side.

Similar letters refer to similar parts throughout the several views. Y

The standards or legsA A, the braces BB, and the cross-piece C constitute the framework of the machine. The shaft D,"operat ing in the bearings E E, is fitted into two pari allel bars F F, extending at rightangles with the shaft. Between one end of saidbars is fastened the receptacle or Achurn G bythe set-screws g g, having an adjustable air-tight lid II, with two weights I I on the other end ltary churns have been made.

olf-said` bars arranged so that they will slide in or outV to counterbalance the weight of said churn and contents and fastened in the desired position by set-screws .I J, said shaft,

churn, and'weights to be rotated by power applied by belt on pulley-wheel L' or by adjustable hand-crank M, fastened to end of shaft N, whereby the milk in the receptacle is agitated and churned to butter.

l In Fig. 2 the mechanism is identical, except that instead of the sliding weights there issubstituted a duplicate churn O, fastened in position by theset-screws p p, which,with its contents,counterbalances the weight of the `other churn G and contents.

.to adjust said weights to accurately counter- ,balance the churn or receptacle and contents and operating mechanism substantially as described'. f

l In testimony whereof I have signed my Aname to this specification in the presence of two subscribing'witnesses.
